A few of my beer drinking buddies have shed a few tears because we can’t get Brew Dog’s Punk IPA here in Ontario anymore. It showed up briefly at local LCBO’s and then vanished just as quickly, never to be seen again.

I remember trying it, and at the time, I thought it fairly easy drinking, but really neither here nor there. I must be clear though, that is in no way a comment on Brew Dog’s brewing, it’s because I’m not the biggest fan of Nelsen Sauvin hops, which they use a lot of. I know, some of you out there are cursing me as I say that, but it’s just my personal taste, nothing more.

I must repeat, my personal taste is in no way a reflection of my opinion of Brew Dog itself. Brew Dogs’ story is extremely inspiring. The way they were able to grow as a result of thinking outside the box in both marketing approach, and financing, have most start-ups drooling. Not to mention their videos are a blast to watch! Check out their take on Punk IPA:

They seem like a bunch of very fun dudes. I seriously wish them nothing but a continuation of their already very successful trajectory.

So, back to our dilemma, since we have no Punk IPA in these parts, what to do? David Thompson, who was over a ways back to collaborate on a brew to clone Samuel Smith’s Oatmeal Stout, brought with him a clone he made of Punk IPA. If I remember correctly, it tasted pretty spot on to what I remember the original tasting like. The signature obviously being the hop profile. I asked him to send me the recipe he had for future reference, which he kindly did. I’ve had it tucked it away all this time, and thought now would be a good time to give it a go as I hate to see tears on my friends faces when hey can’t get a beer they want. (haha, just teasing you Brewtal Honesty!)

Looking to Brew Dog’s site for some verification, I tweaked the recipe slightly to match the information I was able to glean from it:

ABV: 5.6%

OG: 1053

IBU’s: 45

100% Marris Otter Extra Pale Malt

Chinook, Simcoe, Ahtanum, Nelson Sauvin

David’s recipe had no 60 min addition in it, which I found interesting, so I opted to toss a tiny bit of Chinook in at 60mins just for fun. Maybe omitting the 60 min addition is part of the magic? I guess we’ll have to wait and see…

One other thing I don’t know is what kind of yeast they use. I usually start off with my old standby of US-05 first to see if everything else is in line, and then play with the yeast after I’ve established the general idea.

A NOTE ON THE RECIPE: Having the last hop addition calculated at 1 minute puts the IBU’s high at 57, but having them at flameout drops them to 36, even though you’d still get some IBU’s while whirlpooling/standing to chill. I’m going by what David did originally, which was delicious, but to match the original, I may need to tweak this. Either way, the combo is going to provide that special Punk IPA profile.

Building on my previous hopping experiment where I set out to find The Effect of pH on Hop Character, I decided to try something that I’ve been wanting to explore for some time now, the difference in character between whole cone hops and pellet hops. Honestly, I’ve only ever used pellet hops. Probably because of their ease and availability. They’ve produced excellent results in some cases and less than excellent results in others.

Two of my favourite breweries, Sierra Nevada and Victory Brewing, both swear by using only whole cone hops. I’m going to heed their experience and agree that there must be something to it. But what exactly? I’ve heard the extra processing that goes into pelletizing does have an effect on the resulting character, but again, to what extent? Generally I’m of the mind that the less processing in anything food related, the better. Let’s see if this holds true for hops.

I brewed 2 batches over the weekend of my standard Sierra Nevada Pale Ale recipe, exactly the same, except I used whole cone Cascades for the 10 minute and flameout additions in one, and pellets in the other. (pellets were used for the magnum & perle additions in both) Some of you may say that I should have used all whole cone and all pellets to really know the difference, but this is the stock I had on hand. If it doesn’t demonstrate the differences well enough, I will try it again with all whole cone hops. Knowing that the utilization is different for pellets vs. cones, I relied upon Beersmith to calculate the variation and adjusted my additions accordingly to have matching IBU contributions in each batch.

First thing I can say right off the bat, if you’re using whole cone hops for the first time, use a bigger pot, or adjust your batch size to match the pot you have. Whole cone hops are very bulky and will absorb a lot of wort. If in your software (such as BeerSmith) you have the ability to adjust the amount of wort lost to trub, then at least double it as a starting point. (I’d suggest 1 gallon) This will account for the extra wort lost to the whole cone hops.

The second thing I can say is save yourself the frustration of getting your chiller plugged up and use some kind of filter in your brew kettle. A few ways to do this would be to use a bazooka screen, a stainless steel braid, or a blichmann hop blocker. I didn’t think of this beforehand and had to remove my hoses, clear the lines, sanitize everything (to be safe) and try again, 3 times!. Stupid me, what a pain! haha. As a result, I had a longer stand time than I would normally have before I chilled my wort down. I’ll have to keep this in mind when tasting the final beers as it may have contributed more IBU’s to the finished beer.

I’ll let you know what differences I detect in a couple weeks when they’re ready to compare.

I have to say, after kegging these two batches and carbonating them for a few days, I didn’t really notice much of a difference. But after letting them sit for another 10 days or so, the differences became obvious.

Aroma

clearly defined Cascade character with some spicy notes from the 30 minute perle addition

light, balanced maltiness, very clean

light crystal malt aroma

High pH –

muddled hop character, no definition

slightly bready

low fusel alcohol character

Appearance

This is what surprised me the most. After leaving them for about 10 days, I pulled a pint from the low pH batch and BAM! An extremely clear pale ale. I’m not really sure of why that would happen, or the chemistry behind it, but there it was.

Low pH –

decidedly clearer

High pH –

as you can see from the picture, a haze remains

Flavour

Low pH –

crisp tasting with a defined bitterness

clear definition between hop flavour, malt and bitterness

High pH –

confused hop character

no definition between bitterness and aroma

malt character is flat

Conclusion

The beer with the lower pH was clearly a much more enjoyable beer. The flavours are more focused and there is a certain crispness to it. This would be an example to me of the difference between a “good” beer, and a “great” beer.

Firestone Walker is not a name you hear too often up here in Toronto. We kind of live behind an iron curtain of sorts when it comes to the amazing selection of craft beers in the United States.

As my interest in the American craft beer scene deepens, I’ve been hearing more and more about them. It seems like they have something very special going on out there in Paso Robles, California. For starters, they are the only brewery in North America that uses a “Burton Union” style fermentation system, aptly titled the “Firestone Union“.

Of their many award winning beers, one has become a classic example of the west coast style IPA, Union Jack IPA. I’ve been reading Mitch Steele’s IPA book and For The Love of Hops by Stan Hieronymus recently, which has got me very inspired to brew some heavily hopped beers. Lucky for us, in both books, the brewers at Firestone Walker have been kind enough to let us in on how they make it.

Well, the Stone Pale Ale that I brewed is in, and man, this is a seriously good beer. The flavours are very balanced, with a definite caramel flavour to it from the generous amounts of crystal malt (19%). The Ahtanum hops are a unique contribution. Even though I’m expecting the signature citrusy flavours associated with American hops, it’s flavours are slightly illusive, as they seem to really blend in well with the surrounding malt body. I’ve always remembered the saying that “if you can pick out one particular ingredient, then there’s too much of it”. They’re in there for sure, they just don’t jump out and hit you in the face. This beer is quite complex for having such a straight forward recipe.

These numbers are not very far off my own water here from Lake Ontario, but the sulphate level is a bit higher at 85ppm as compared to mine of 28.6ppm. I’ve noticed that by using Magnesium Sulphate (Epsom Salt) as opposed to Calcium Sulphate (Gypsum), the resulting enhancement is slightly different. I’m not finding it as ‘harsh’ as I sometimes get with having too much gypsum in my beers. Maybe it’s just all in my head, because sulphate is sulphate, right? Maybe it’s the sulphate/chloride balance? I’m not sure. My point is, I think the water profile definitely made an impact on this beer in the form of added complexity.
